VEHICLE-TIRE.

Specification of Letters Patent. Application filed October 12, 1906.Serial No. 338,542

Patented Jan. 4, 1910.

Another object of the invention is the,

production of a sectional tread for vehicle tires adapted to permit ofreadily replacing a damaged or worn section with a new section.

A further object of the v production of a tire provided with a treadhaving no tendency to injure the roadway by suction or otherwise. Afurther object is the production of a cover adapted to be applied to theouter casing of a tire to protect the tire proper from punctures andsimilar accidental injuries.

A further object is the provision of such a rotective cover which shallbe readily applicable to tires of the form now in common use.

In the accompanying drawings Figure 1 through a tire and felly,illustrating some of the features of my invention. Fi a. 2 is afragmcntal side elevation of the t1rc and felly shown in Fig. 1. Fig. 3is a fragmental outer peripheral view of said tire. Fig. i is afragmental outer peripheral view lllustrating an alternative ablypossessing resiliency,

form of tread surface. Fig. 5 is a'detail View of a modified form ofprotective casing. Referring to the drawings, 1 designates the felly and2 a channel rim secured tiiereto in any suitable manner and extendingabout the periphery of the wheel. 3 is secured to the wheel by means offlan es 4; on said casing lying within the over anging walls 0" thechannel rim 2, said tire casing being held in place by the pressure ofthe air within the inner tube 5 of the tire.

The tire casing 3 is provided'with a wearing surface or tread consistingof blocks 6 of rubber or other suitable material, prefersaid blockshavinvention is the The tire casing I place a worn or damaged ing aniuner'surface 7 which is curved to conform to the periphery of the tirecasing. he blocks 6 are adapted to abut side by side to form a seriesextendin about the peripher of the tire, said blocks being cementec upona strip of canvas or other suitable material 8, said strip being of awidth suflicient to extend substantially halfway around thecross-sectional periphery of the tire casing. Upon their outer sideseach of the blocks 6 is provided with a bearing portion 9 ofsubstantially rectangular form, said bearing portion being of less widththan the body of the block 6 so as to space the bearing portions apart.If desired, each of the blocks 6 may be provided with two bearingportions 9 slightly separated from each other, as indicatedin Fig. 4.

The blocks 6 are secured in place about the periphery of the-tire bymeans of straps 10 formed of rawhide, fabric, or other suitablematerial, and being provided at their ends with means for engagin twoflanges'll extending one at each sic of the wheel and lying in contactwith the channel rim 2. In the form shown in Figs. 1 and 2, the engagingmeans for each end of each strap 10 consists of a piece of wire bent toprovide books 12 adapted to engage the in-turned edge 13 of the flange11, the bar 14 connecting said hooks lying within the folded and rivetedend of said strap. Intermediate their ends the straps 10 extend over theblocks 6, said straps having openings. 15 therein adapted to receivethe'portions 9 or 9 of said blocks. The middle portions of the straps 10are wider than the end portions, and the edges of the middle portions ofadjacent straps overlap, as shown in Fig. 2. The overlapping portionsare secured together by means of rivets 16 passing through saidoverlapping portions and a cleat 17 of steel or other suitable material.As will be seen, the straps 10 form a protective casing for the tire,adapted to protect it from accidental injuries.

The strap 10 maybe formed of various materials, and in Fig. 5 I haveshown a strap comprising leather side-portions 18 and a metallic middleportion 19 adapted to fit over the blocks 6. To the ends of the leatherside-portions, 18 are attached books 20 or other suitable means toengage the flanges 11.

In use, when it becomes necessary to reblock 6, the tire is new blockscemented to said canvas.

deflated, a suflicient number of straps 10' disengaged at one side fromthe flange 11, and the disengaged ends thrown over to the other side ofthe tire out of engagement with the blocks 6. The damaged block orblocks may now be stripped from the canvas 8 grid e straps 10 are thenplaced across the blocks and engaged With the flange 11, and the tireinflated to hold the protective casing and tread in place. tread surfaceof the, tire consists of a series of comparatively thick rubber bearingportions 9 or 9 and steel cleats 17 alternating in position, therebyaffording, excellent protection against injury to thetire casing orinner tube. The rubber bearing portions 9 v or 9 being comparativelylong (having reference to the width of the tire), 20

.10 may be made of materials skidding 1s prevented. The bearing portions9 or 9 being spaced apart, the tendency of the tire to clin to theroadway by suction, as do tires of the common form, is entirelyobviated. The straps 10 constitute a protective ,casing which, inconjunction with the flanges 11, completely incloses the tire. Thestraps which are strong and durable and not liable to puncture orcutting, such as raw-hide or sheet metal. I

I claim as my invention:

- 1. A tread for pneumatic tires comprising resilient blocks each of a'width to extend substantially from side to side of the tire and havinga substantially flat outer surface and an inner surface curved toconform to the periphery of the tire casing, a resilient projection onthe outer side of said blocks, and means for securing said blocks to thetire, said means comprising a series of overlapping elements havingstiffened portions.

2. A tread for tires comprising resilient blocks having substantiallyflat outer surfaces, a resilient projection upon the outer side of eachof said blocks, straps for securing said blocks to the tire, the middleportions of said straps overlapping, and transverse cleats overiyingsaid overlapping portions and secured thereto between said projections.

3. A tire structure comprising a felly; a tirecasing; a series ofabutting resilient It will be seen that the blocks forming a continuous,unbroken protective tread extending about the peri hery of said casing,the inner surfaces 0.. said blocks being curved to conform to theriphery of the tire casing; a strip to which the inner surfaces of saidblocks are cemented; a resilient bearing projection on each of saidblocks; straps; cleats for securing said straps at their middleportions, having openings through which said bearing projections extend;hooks on the ends of said straps; and flanged members extending alongsaid felly and adapted to be engaged by said hooks.

4. A tire structure comprising a felly; a tire casing; a series ofabutting resilient blocks forming a continuous, unbroken protectivetread extending about the periphery of said casing, the inner surfacesof said blocks-being curved to conform tothe periphery of the tirecasing; a resilient bearing projection on each of said blocks; straps;cleats for securing said straps together at their middle portions, saidstraps having openings through which said bearing projectionsextend;hooks on the ends straps; and flanged members extendin along said fellyand adapted to be engaged by said hooks.

v 5. A tire structure comprising a felly; a tire casing a series ofabutting resilient blocks forming a continuous, unbroken protectivetread extending about the periphery of said casing, the outer surfacesof said blocks being flat and the inner surfaces thereof being curved toconform to the periphery of the tire casing, ing of a width to extendsubstantially from side to side of the tire casing; a resilient bearingprojection on each of said blocks extending transversely of the tire;protective means overlying said blocks between said bearing projections;a leather covering for the sides of the. tirecasing, said coveringextending from said blocks to a point adjacent to the'felly; and meansfor securing the lower edges of said side coverings in place.
